Great Planes Patriot XL Kit - GPMA0450 - Manual (Page 25)

Before finishing the bottom of the fuselage,
we’ll mount the wing.
❏
1. Fit the wing into the fuselage. Taking accurate
measurements, center the wing from side-to-side. Holding
the wing in position, use the holes in F2 as a guide to drill
1/4" [6.4mm] holes through the leading edge of the wing.
❏
2. Remove the wing. Use the holes in the wing as a guide
to drill the holes the rest of the way through the webbing
inside the wing.
❏
3. Round one end of both 1/4" x 3-1/2" [6.4 x 89mm] wing
dowels. Use 30-minute epoxy to glue both dowels into the
wing with 3/8" [10mm] protruding.
❏
4. After the wing dowel epoxy has cured, fit the wing to
the fuselage. Measure the distance from the end of the
fuselage to both wing tips. Pivot the wing until the distances
are equal as show by B=B in the sketch.
❏
5. Glue the die-cut 1/8" [3mm] plywood wing bolt plate
to the bottom of the wing as shown. Double check the
measurements taken in the previous step to be certain the
wing is centered.
❏
6. Using the holes in the wing bolt plate as a guide, drill
#7 holes through the wing and the bolt block in the fuselage.
Remove the wing.
❏
7. Use a 1/4-20 tap to cut threads into the holes in the bolt
block. Add several drops of thin CA to the threads, allow to
fully harden, and then retap the threads.
❏
8. Enlarge the holes in the wing only with a 1/4" [6.4mm]
drill.Test fit the wing to the fuselage with two 1/4-20 x 2" [50mm]
nylon wing bolts. Make adjustments where necessary.
